Ok so this is what's up. A guy wants to trade his 95 SE S14 Automatic KA for my 89 Fastback with a Blacktop SR. He wants his KA in my Fastback. So i figure I use my blacktop to put in the S14. What do I need to make this possible? Please help....

from my understanding all the original motor mounts from the sr20 fit perfectly into the 95 s14. so theres is no custom work to be done on that side ur harness stays the same u just rewire it and extend what ever cables u need to plug all sensors and wat not.
in regards to tha tranny i have no idea if the us 240s are rear wheel drive if they are then that should be plug n play also. wait for other replies to post on ur thread to confirm some of these statements. peace

Correct. Assuming you have the SR running in a single cam S13 with all supporting mods (namely power steerring) all the mechanical parts should swap over.

ur harness stays the same u just rewire it and extend what ever cables u need to plug all sensors and wat not

Incorrect. You do not need to extend any sensor. You do need to rewire the ECU relay because the S14 has the ECU relay integrated into the engine harness whereas the S13 has the ECU relay integrated into the body harness.

You also need to integrate the S14 wiper into the engine harness whereas the S13 has the wiper wiring in the body.

in regards to tha tranny i have no idea if the us 240s are rear wheel drive if they are then that should be plug n play also

Also incorrect.

First, every single 240SX is RWD.

Second, you will have to rework the lower harness into the S14 body harness with auto from the factory.

You need at least the alternator wiring and starter wiring. The other optional sensors on the lower harness are the oil light, reverse light, and VSS. You can ignore the neutral switch.
